Your music library should feel like yours. Flex Music is an independent music player and playlist manager for personal Plex Media Server libraries. Sign in with Plex, choose your server and enjoy your music at home, remotely or offline. BROWSE AND PLAY Explore artists, albums, tracks, playlists, genres and moods. Search inside large playlists, rate tracks back to Plex, and keep browsing while the mini-player plays. Expand Now Playing for artwork, synced lyrics when available, visualizers and the waveform progress bar. YOUR QUEUE, YOUR WAY Use Play Next to put a track first, or Play After Next to add it after your manually queued tracks. Assign these actions to your playlist swipes. Manage Up Next and Previously Played, reorder playlists, add whole albums and clone playlists. OFFLINE AND DATA SAVER Download your music with no paid track limit. Choose storage limits and keep favourites offline. Data saver asks your Plex server to convert audio to your chosen bitrate, with separate Wi-Fi and cellular preferences and measured transferred-data totals. Conversion depends on your server; data saved is compared with the original media size. MADE FOR YOUR SCREEN Choose themes, artwork effects and visualizers. Larger displays have room for the player and queue side by side. iPhone Duo adapts from a compact cover-screen player to a stacked portrait layout and a side-by-side player and queue when opened in landscape. Controls stay clear of the system strip, and your player and queue are retained as the layout changes. Music casting is free on supported receivers. Lyric casting brings available lyrics to Google Cast displays with Flex Music Pro. FLEX MUSIC PRO Free: browsing, playback, Smart Search, ratings, on-device lyrics, music casting, themes and visualizers, offline downloads, the Pinned Playlist widget, and editing playlists up to 100 tracks. Pro unlocks editing larger playlists, saving smart playlists and listening sessions, premium home-screen widgets, alternate app icons, navigation icon themes and styles, and lyric casting. The Apple Watch companion is also included with Pro. CarPlay and Siri playlist playback are free. Monthly, yearly and lifetime plans unlock the same Pro features. Purchases are processed by the App Store and can be restored from Settings. Lifetime is a one-time purchase; subscriptions renew until cancelled in your store account settings. REQUIREMENTS A Plex account and access to a Plex Media Server containing a music library. Network access to that server is required for streaming and library management.

Sparsi is a straightforward music player for the audio files you already own. Import songs directly from the Files app — no syncing, no cloud account, no subscription. Everything plays from your device, offline, exactly as you'd expect from a local player. IMPORT YOUR WAY Bring in audio files from Files, iCloud Drive, or any Files-connected storage provider. Sparsi reads the embedded tags automatically so your library is organized from the moment it lands. EDIT METADATA Fix a wrong title, artist, or album — or add artwork from your photo library — right inside the app. Sparsi keeps the original file tags untouched on disk, so edits are always non-destructive and can be reset back to the source at any time. BUILD PLAYLISTS Group songs into playlists, reorder them, and pick custom cover art. Your playlists live alongside your library, always a tab away. BROWSE AND SEARCH Sort your library by title, artist, album, or date added. Search finds a track in seconds, even in a large collection. PLAYBACK THAT STAYS OUT OF YOUR WAY Lock-screen and Control Center controls, background audio, a persistent mini-player, shuffle, repeat (off/all/one), and position memory so playback picks up exactly where you left off — even after the app was closed. PRIVACY BY DESIGN Sparsi doesn't require an account and doesn't stream anything to a server. Your library stays in your device's storage. Photo library access is used only if you choose artwork for a playlist — nothing is uploaded anywhere. Sparsi is built for anyone who already has an audio collection and just wants a fast, uncluttered way to listen to it.
